A feasibility and pilot additive randomised control trial of attachment security priming during behavioural activation.

Background: There is some initial evidence that attachment security priming may be useful for promoting engagement in therapy and improving clinical outcomes.

Aims: This study sought to assess whether outcomes for behavioural activation delivered in routine care could be enhanced via the addition of attachment security priming.

Method: This was a pragmatic two-arm feasibility and pilot additive randomised control trial.
